Lowest lowering springs you can go with is Vogtlands which are almost impossible to find. Your next option are Zzp or SSC. Haven't heard enough about the Zzp springs to recommend them nor do I enjoy their customer service so I avoid buying from them as much as possible. Get the SSC mild drop shouldn't need a camber kit but again you will find out if you do after a alignment or you could have the struts slotted. With lowering it you take the change of something breaking prematurely. All of this has been answered in Bios thread.
